oblgny - there is a set of CS3.5 with the eq at College Hifi in Chattanooga. I listened to them last week with a Mac amp, the eq was not hooked up but I will try go try to hear them again with the eq just out of curiosity. They sounded great, very neutral and clean across the entire sound spectrum.
Jazzman7 - I am using the Legacy Audio High Current Amplifier by Coda. It is 220wpc @ 8ohm and 380 wpc @ 4ohm. Coda branded amps don't show up very often and are pricey. They show up on ebay sometimes for $800-900. Other amps I tried with the 1.6 were the bryston 4b, butler, classe dr-9, musical fidelity a3cr, jaton operetta and conrad johnson mf2300A. The conrad and coda were my favorites.
Here is an interior shot of the coda

I opened up the 2.4 speaker to remove the tweeter/midrange which I though was broken. It turns out the white lead was disconnected. I tested with a multimeter across the terminals and it got a 2.8-3 ohm reading, which seemed good so I resoldered it and also used a q-tip to push out a divot in in the tweeter dome. The speaker sounds great now, I am pretty exited and I will post some more comments this evening, I did notice you can tell when one speaker has the grill on and the other doesn’t.
I was reading through the tread and there are a lot of posts on upgraded crossovers, is there any particular post which has a summary of which parts need to be upgraded due to age and which parts are the best for sq? Are there completed crossovers or kits that can be purchased?
